MATERIALS SELECTION FOR WET CYLINDER LINER

Abstract

––Introduction: Cylinder liner is used in engine block to give a wear protective surface for piston and piston rings. Problem statement: However, continuous exposure to high pressure, high temperature, vibration and friction inside combustion chamber could damage and reduce cylinder liner efficiency. Objective: Therefore, the purpose of this study is to find a suitable material for cylinder liner that can withstand the stated constraints. Methods: By using Cambridge Engineering Software (CES), a list of candidate materials was compared to each other in terms of general properties, mechanical properties, thermal properties and material processing energy. Results: The results provided a list of 5 suitable material (Carbon Steel, Cast PH Stainless Steel, Cast Nickel-Chromium Alloy, Low Alloy Steel and Wrought PH Stainless Steel) for the cylinder liner. Conclusions: Finally, as based on the critical characteristics (durability, composition and operation in exterme combustion), Cast Nickel-Chromium Alloy, Inconel 713C, as cast was indentified as the most suitable material for the wet cylinder liner application.
